The ATC are a bit aggressive but also a tad more dynamic, but less musical. Spendor also makes an affordable subwoofer. ATC has very shaky US distribution and only a couple of dealers. Well made, but Spendor's are just nice and neutral and sweet! That is why I am a Spendor dealer not and ATC dealer--and ATC's importer is less than 100 miles from my store.
